Description
Technical field
The present invention relates to a kind ofly for example make the method for refined sugar sugarcane crude sugar juices or the sugar beet crude sugar juices, the invention still further relates to the device of this method of enforcement from syrup.
Background technology
At present, making the processing of refining sugar that refined sugar (or white sugar) comprises set amount from sugar cane juice, is that the purified that carries out of set amount replenishes processing then.
Schematically, the key step that sugaring is handled is, by smashing to pieces-crushing sugar cane or make crude sugar juices by lixiviate and extract sugar; Clarify this juice by adding lime,, concentrate resulting juice by in the carbonic anhydride and the latter's juice (under the situation of beet) and the juice that diafiltration was handled like this, and generally be three steps sugar is carried out crystallization and purging, this will make brown sugar and waste molasses.
In refining process, wherein to the operation that this brown sugar carries out be mainly contained: the step of step, crystalline step and purging of eliminating the purification step (crystal being washed purging then) of plane of crystal impurity, the sugar that obtains being carried out step, the decolouring of dissolved step, purification with sugared saturated aqueous solution.For the syrup that makes higher degree is carried out crystallization, this last operation than the sugaring complicated operation many, and need two to three spraying dryings (jet), the sugared purity of the liquid after the last spraying drying is still very high, and its dissolved sugar will extract by 3 or 4 additional crystallisation steps, it is very dark colour sugar and a kind of waste molasses that so-called " the low product that waits " crystallization causes finished product, and this dark colour sugar will be again circulates from beginning at first of refining.We notice that the high viscosity of this product is suppressing this crystallization, and this crystallization all is expensive on material and energy expenditure.
In the past few years, worked out the quality that several method improves the sugar in sugaring stage.
Thereby in U.S. Pat 5 554 227, people such as Kwock have proposed that a kind of to make low colourity with membrane filtration, operation softening and that purify be the method for the brown sugar of so-called SVLC " Super Very Low colour " (super low look) by a series of.This method can be simplified the refining of brown sugar, has especially reduced operation refining and that purify.It also can carry out a kind of chromatographic step and reclaim sugar and waste molasses, and thereby improves the extraction output of this sugaring.This chromatography generally can cause two kinds of products, promptly a kind of extract of rich sugar and a kind of sugar of purifying of waiting that contains impurity.
In International Application No. WO 95,/16 794, people such as Mc Kearny have proposed to use the method for chromatographic purification sugar beet juice before purifying, soften and concentrating back and crystallization.This document discloses a kind of purity (sugar is with respect to the weight percent of dry substance) and has been about 90% syrup, and this chromatography can be increased at least 94% with this purity.The crystallization of this class syrup is divided into spraying drying 3 times, and the waste molasses of a kind of white sugar and a kind of purity about 60% is provided.
But it is unsuitable economically that this method is applied to sugar cane juice.
In fact, when producing white sugar by sugar cane juice, require to have than the more highly purified syrup of beet syrup, promptly purity is 94%～98%.Under this condition, carrying out crystallization by 3 spraying dryings, to produce the white sugar of high yield be impossible, because in order to keep the quality of commerieal sugar, crystallization can not surpass 50%～60% of existing sugar when each spraying drying.
Ways of addressing this issue can be to prolong crystallization time by the so-called spraying drying that drains of 2 or 3 steps, and this can cause when carrying out refining and wait the product periodic crystallisation to hanging down, and this is that we will avoid as possible.
Summary of the invention
Thereby the objective of the invention is to address the above problem with the method for economy, and provide a kind of for this reason and for example make the method for refined sugar (or white sugar) sugarcane crude sugar juices or the beet raw sugar juice from containing the sugar and the syrup of impurity, the feature of this method is that it comprises following operation:

Two steps or surpass this extracting solution of two one step spray-dryings and carry out crystallization obtain refined sugar and a kind of liquid, and
Aforesaid liquid is mixed with this remollescent syrup, then two kinds of liquid that blend together are carried out the chromatography operation.
Therefore, the method according to this invention does not need to prolong crystallization, and has reclaimed the liquid that the last spraying drying of crystalline produces, and obtains the remollescent syrup with this concentration operation and carries out the chromatography operation jointly.
This will no longer produce waste molasses, and the non-sugar (impurity) in the syrup has been eliminated in chromatographic purification waste liquid part, and the sugar in the final liquid reclaimed in described chromatographic grading extraction, and this has increased overall yield.
Preferably, the method according to this invention also comprised before carrying out tangential flow filtration operation this syrup is carried out a cleansing operation; Non-dissolved matter matter has been eliminated in this cleansing operation.
In addition, this tangential flow filtration operation is preferably selected a kind of from tangential micro-filtration, tangential ultrafiltration or tangential nano filter; This filtering technique is to be undertaken by suitable membrane, is very known in prior art.
Should softening operation preferably include the exchange operations of being undertaken by ion (positively charged ion) exchange resin, for example be Na
+Type.
